The historic inhabitants of the area were the indigenousUmatilla,Cayuse,Walla Walla, andColumbia Indians, descendants of peoples who lived in this area for thousands of years. The earliest European settlers established a mission nearPendleton in 1847. The territorial government organized Umatilla County in 1862 from the largerWasco County.
Hermiston's early development was plagued by rivalry between The Maxwell Land & Irrigation Company and developers Skinner & Newport, who both fought to establish their own town of Hermiston in the exact same spot, centrally located in the irrigation district along theOregon Railway and Navigation Company's main line. While Maxwell was able to secure the train depot on the West side of the tracks, initially naming it after themselves, Skinner & Newport filed their own Hermiston plat directly across the tracks in November 1904, beating the Maxwell Company's filing by two days.[7] With neither side willing to cede to the other, two separate business districts formed on either side of the tracks, Hermiston Avenue on the West side and East Main street (there is no West Main Street) on the East side, defiantly placed one block off so they didn't align. Each district featured its own bank, hotel and mercantile but East Main street would eventually win out.[8]
The rival developers eventually settled their differences and on July 10, 1907, the two towns were incorporated as a single Hermiston. Colonel J. F. McNaught, an early settler in the region, is credited with originally coming up with the Hermiston name, which was taken fromRobert Louis Stevenson's unfinished novelWeir of Hermiston.[9]
The greater Hermiston region began to see irrigated agriculture in 1908, with the completion of theU.S. Bureau of Reclamation's Umatilla Basin Project in the form of Cold Springs Reservoir.[10] The region saw modest growth until the outbreak ofWorld War II, when theUmatilla Army Depot was constructed, causing Hermiston's population to jump from 803 at the 1940 US Census to 3,804 in 1950. The region continued to experience modest growth for the next several decades until the 1970s, when low power costs coupled with the development ofcenter-pivot irrigation resulted in a significant expansion in agricultural acreage put in to potato production. The expansion of potato production coincided with the development of large potato processing plants byLamb-Weston andSimplot, focusing on frozen potato products. The associated economic development drove Hermiston's population to nearly double from 4,893 in 1970 to 9,408 by 1980. The 1990s brought additional large employment developments to the Hermiston region in the form ofTwo Rivers Correctional Institution, a Wal-MartDistribution Center, expansion of the Union Pacific Hinkle Rail Yard, and beginning of theUmatilla Army Depot's Chemical Weapon Incineration process. The 2000s have seen continued growth and diversification of the regional economy as Hermiston has grown to a population of 19,354 at the 2020 Census and has become a regional center for commercial and professional services.
The city is also known for itsWatermelons, which are part of its branding.[11]
Hermiston serves as the retail and services center for much of western Umatilla County,[12] as well asMorrow County and parts ofGilliam county. Hermiston's Local Trade Area, which describes the area where people will travel to purchase items on a weekly basis, stretches fromPendleton on the East, theColumbia River to the North,Heppner to the South, and Gilliam County to the West. There were 46,000 people living within Hermiston's Local Trade Area based on 2010 U.S. Census data.[13] Despite a relatively robust local retail & services market, Hermiston experiences significant retail sales leakage to theTri-Cities for items purchased on less than a weekly basis. The Tri-Cities, located approximately 30 minutes north of Hermiston in Washington, had a metro-area population of 275,740 as of April 1, 2014, making it the fourth largest metropolitan area in Washington.[14]
The Greater Hermiston area, which encompasses theHermiston,Umatilla,Stanfield, &Echo zip codes, and equates to a less than 10-minute commuting distance, has seen strong job growth since 2012. The Hermiston area added 2,930 jobs from 2012 to 2022, which equates to 91% of all net job growth inUmatilla County over that time.[15] More recently, Greater Hermiston accounted for 114% of Umatilla County job gains from 2019 to 2022 as a result of 1,121 jobs added compared to net losses of 74 and 48 jobs inPendleton andMilton-Freewater respectively.[16]
Hermiston has the largest 30-mile-radius workforce in Eastern Oregon. According to 2022 U.S. Census estimates, there were 144,664 people actively employed and living within a 30-mile radius of Hermiston;[17] in comparison, there are 101,119 in the next-largest 30-mile regional Labor Shed in Bend.[17] Hermiston-area employers benefit greatly from the proximity of the Tri-Cities in Washington which, based on light traffic, and easy freeway access, is approximately 30–35 minutes to the north of Hermiston. This proximity also allows dual-income households good access to employment opportunities for both wage earners.
Riverfront Park features open grassy space, and access to more than 2 miles of paved walking trails.
The City of Hermiston Parks Department maintains 15 parks, 15 landscape areas, and 100-plus acres for the enjoyment of the community. In addition to the developed parks, the department also has 50 additional acres planned for future development.[19] Recent major enhancements include the additions of Riverfront Park, the Oxbow Trail, and continual additions to the Hermiston Family Aquatic Center. Riverfront Park features 16 acres of open grassy areas alongside the Umatilla River, as well as nearly a mile of paved walking paths, with picnic shelters, restrooms, and fishing access. A 1.8-mile paved walking path, named the Oxbow Trail, was added in 2015 to connect Riverfront Park with the north side of town near Good Shepherd Medical Center. The Trail winds through protected wetland area for nearly the entirety of its length and also connects to Harrison Park.
Hat Rock, located on theColumbia River near Hermiston, was one of the first landmarks of the area noted byLewis and Clark in their journals.[20]TheHermiston Butte features several easy hiking trails accessible from Butte Park, the Hermiston Family Aquatic Center, and Good Shepherd Medical Center
Hermiston's recent population growth is due to its proximity to large cities in thePacific Northwest and its location along two major freeways.[22][23]
According to theKöppen climate classification system, Hermiston has asteppe climate (Köppen BSk). This gives the area hot dry summers with high daytime temperatures which do cool considerably overnight, and relatively cold winters which typically yield several snow storms per year with relatively minimal accumulation. On June 29, 2021, a max temperature of 118 °F (48 °C) was recorded in Hermiston, which is just one degree below the new all-time record high temperature for the State of Oregon, which was set at the nearbyPelton Dam, which is also in Jefferson County, on the same day.[24]

Hermiston High School competes at the 3A level in theWashington Interscholastic Activities Association. This cross-state membership was approved by the WIAA in 2017 in recognition of the lack of comparable sized large high schools elsewhere inEastern Oregon.[40] The second largest High School in Eastern Oregon wasPendleton, with only 815 students, compared to Hermiston's 1,703. The WIAA membership allows HHS to compete in the Mid-Columbia Conference against high schools from Kennewick, Richland, Pasco, and Walla Walla, Washington and significantly reduce travel times for conference games.
